4 SPECIFICATION formng'part of Letters Patent No. 256,954, dated Aprl 25, 1882.

Application filed November 16, 1881. (Xo model.) Patented T 0 all 'whom it may conce'n r Be it known that I, ANTON BESSER, of Vicuna, Austria-Hungary, have iuvented a new and Improved Apparatus for Cleaning Grits, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved apparatus for cleaning grits, grains, seeds, and analogous substances thoroughly, continuously, and in an economical 'mannein v The invention consists in a novel Constructiou and arrangement of'the paris, as heroinafter described and claimed. i

Reference is to be had to the aceoupanying drawing, forning part of this specification, in which a longitudinal sectioual elevation of my improved apparatus for cleaning grits, 850., is shown.

A box, A, made of Wood, netal, or other suitable material, is provided on top with a lopper or funnel, B, into which the material to be cleaned--such as grits, grain, &0.-is poured. At the outlet of the t'unuel or hopper I have provided an inwardly-swinging automaticall y-closin g gate, C, which can be opened by the descending grits, but prevents air from passing into the box A. This gate G may be replaced by rollers or other equivalent devices serving the same purpose. From the lower end of theinclined partition B', forming the hopper B, the grits slide through the slot D and drop throughthe space X upon the inclined partition 0. A current of air enters through an opening, E, closed more or less by a hingcd or pivoted gate, N, and this current of air blows the lighter particles over the upper edge, H, of the triangular prisn F, pivoted or hingcd on the upper edge of the iuclined partition O. The heavier particles carried over the edge H drop through the space J upon the inclined partition S,and the lighter particles drop through the space K upon au inclined hingcd or pivoted partition, P or P', at the bottom of the box A, and the very lightest particles are carried over the partition L and drop into the chute or channel M, which is connected with a suctiou apparatus. The heavy partieles which have not been carried over the edge H of the triangular prisnF slide down the inclined partition O and through the in Austria August 31, 1881, and in Hungary August 31,1881.

slot D' at the bottom of this partition anddrop through the space X' upon the partition O'. Acurrent of air passing through the opening E' carries the lighter particles over theinclined partition S upon the inclined partition S'. From the inclined -partition O' the particles drop through the slot D and space X upon the inclined partition O and slidedown this partition into the chute M'. -Theparticles on the inclined partition S' drop through the slot I' upon the partition S and slide down the same into the chute M. The particles that have-dropped through the space `K will be conducted into the chute M it' the hingcd gate or partitiou P is in the position shown iu full liues; but if its swunginto the position shown in dotted lines the particlcs will drop upon the inclined partition P' and slide down the same into the chute M The hingcd or pivoted gatcs R' R R serve to prevent air from entering into the box` A from below.

The cleaued grit is divided into four differcnt grades, according to weight, each kind passing down a separate and distinet chute.

The particles of grits, grains, &c., are subjected to the action of the several currents of air entering through the openings E E' E several times-that is, the operation is continuous, the air thatpasses over the lower partitions'ot' the front vertical row of partitions again acting upon those particles that drop from above in the second vertical row of partitions and have been acted upon by the current of air eutering through the upper openings. The inclined partitions are so arranged that their lower faces will be substantiaily on the same inclined planes and the angular slots I. I' will be left between them, the upper parts of said slots being parallel with and the lower parts gerpendicular to the lower faces ot' the said partitions. The front wall of the box through which the air-openings are made is composed of prismatic pieces beveled or inclined iuward in two directions from the said openings to form the inclined planes Y Y' Y Y the lower faces of which are in the same IOO inclined plane with the lower faces of the partitions, and between them and the bottom of the hopper and the inclined partitions O O' .are formed, in the same manncr as shown and described, angular slots D D' D The number of partitions O and P a'ranged above each other and the corresponding numberof air-current openings can be varied as the circumstances may rcquire.

The prisms F F', &c., may be made solid or hollow and of any suitable material, such as Wood, china, glass, metal, &0. As these prisms are pivotd or hinged on the upper ends of the inclined partitions O O', &c., they can be adjnsted to have a greater or less inclination, as

shownin dottcd lines--that is, the upperedges, H H', &c., of these prisms F F', &c., can be moved a. greater or less distance from the slots D D', &(5., according to the nature of the inaterial tobe cleaned, for accordingly as the upperedges, H Ll', 850., of these prisms F F' are a greater or lcssdistance from the slots D D',

&`c., a greatcr or less quantity of the material will be blown over the cdges H H The inclination of the partitions O or P and the depth of the chest, like all other parts of the apparatus, may be varied as circumstances n ay require.

with the air-openings E E' E and the adjustable hin ged gates N N' N of the inclined partitions O O' S S' and the pieces having their lower faces, Y Y' Y arranged on the same inclined planes and arranged to leave between them the angular slots D' D I' 1 the upper parts of said slots being parallel with and the lower parts perpendicular to the lower faces of the said partitions and inclined planes, substautially as and for the' purpose set forth.

2. In an apparatus for cleaning grits the eonbination ot' the box or chest A,`the pieces presenting the inclined planes Y Y' Y the inclined partitions O O' 0 having their lower faces arran'ged on the same inclined planes as those of said pieces, and arranged to leave angular slots at their points of nearest approach thereto, and the ad justable triangular prisns F F' F hinged to the upper edge ot' the inclined partitions O O' 0 directly facing the said slots, substantially as and for the purpose set forth.

3. In-an apparatus for cleaning grits, the combination, with the box or chest A, provided with a series of air-openings and adjustable gates therefor, the hopper B, formed with slot D, and the inclined partitions O O' O S S' S, and the pieces presenting on their lower faces the inclined planes Y Y' Y arranged substantially in the same inclined planes as those of partitions O O' S S', of the adjustable triangular prisms F F' F?, hinged to the upper edge of one series of inclined partitions, the vertical partition L, and the chutes M M' M M substantially as and for the purpose set forth.
